Swingable exercise bike

Abstract

A swingable exercise bike includes a base having a first pivot portion for a bike body to be pivotally connected to the first pivot portion so that the bike body can swing left and right relative to the base. Left and right sides of the first pivot portion are provided with first connecting rods. The first connecting rods each have one end pivoted to the base and another end extending in a height direction and pivoted to a second connecting rod. The second connecting rod is further pivoted to the bike body. When the bike body swings left and right, the first and second connecting rods are pivoted. The two second connecting rods are connected with a cushion device disposed in a horizontal direction, which can generate a damping effect when the two second connecting rods are pivoted by the bike body, thereby cushioning the swing of the bike body.

What is claimed is: 
     
       1. A swingable exercise bike, comprising:
 a base having a pair of first pivot portions respectively pivotally connected to a bike body at opposing longitudinal ends of the base for enabling the bike body to swing from side to side relative to the base; 
 two first connecting rods and two second connecting rods disposed at each of the opposing ends of the base, the two first connecting rods at each of the opposing ends of the base being respectively located at opposing sides of a respective one of the first pivot portions, the first connecting rods each having one end pivotally connected to the base and another end extending in a height direction and pivotally connected to a corresponding one of the two second connecting rods, each of the two second connecting rods being further pivotally connected to the bike body adjacent a corresponding opposing end of the base; wherein when the bike body swings from side to side, the first connecting rods and the second connecting rods at each of the opposing ends of the base are respectively pivoted; 
 a pair of dampers disposed at each of the opposing ends of the base in a horizontal direction, and each of the pair of dampers having opposing ends each being connected to a respective one of the corresponding two second connecting rods for generating a damping effect when the corresponding two second connecting rods are pivoted by the bike body. 
 
     
     
       2. The swingable exercise bike as claimed in  claim 1 , wherein the base is provided with a pair of second pivot portions at each of the opposing ends of the base, each of the pair of second pivot portions being respectively located at the opposing sides of a respective one of the first pivot portions to be pivotally connected to corresponding first connecting rods, and each of the second connecting rod at each of the opposing ends of the base has a length less than a distance between the respective one of first pivot portions and one of the corresponding second pivot portions. 
     
     
       3. The swingable exercise bike as claimed in  claim 1 , wherein two pivotal positions at which the two second connecting rods at each of the opposing ends of the base are respectively connected to the bike body are at a same height. 
     
     
       4. The swingable exercise bike as claimed in  claim 1 , further comprising two supports at each of the opposing ends of the base, the two supports being located at respective opposing sides of the respective one of the first pivot portions and fixed to a corresponding one of the second connecting rods, and two opposing ends of a corresponding one of the pair of dampers each being pivotally connected to a respective one of the two supports at each of the opposing ends of the base.
